ELECTRIC TRAINS R MTH P-2 BOX CAB ELECTRIC ENGINE OPERATING INSTRUCTIONS Thank you for purchasing the MTH Electric Trains P-2 Box Cab locomotive. This ¼” scale reproduction of the famous P-2 Box Cab locomotive measures just over 21” in length and weighs almost 8 pounds. Despite its scale size, the locomotive is capable of operating on O-72 3-rail track with most compatible AC transformers (see the chart on page 31 for a complete list of compatible transformers and wiring instructions) and is completely compatible with most other 3-rail locomotives, rolling stock and accessories. The locomotive is equipped with several deluxe features that are simple and fun to operate. Each feature is described among the following pages which should be read before the engine is operated. For those of you who can’t wait to get started, the Quick Start Basic Operating Instructions found on Pages 3 and 4 should be read so that you understand the basics of the operating system. Please note that some features are only found in the Proto-Sound® models and are marked as such. Features not marked as Proto-Sound® features are available in all models.

Despite these advanced features, the P-2 Box Cab is easy to operate with any compatible standard AC transformer (see the compatibility chart on page 33). The P-2 Box Cab locomotive is controlled by a Proto-Sound® DCRU® electronic reverse unit. The reverse unit operates in the same manner that all reverse units function by using forward, neutral and reverse states that are entered each time the throttle is turned on and off or by using the transformer direction switch (if so equipped). The P-2 Box Cab locomotive is controlled by a Proto-Sound® DCRU® electronic reverse unit. The reverse unit operates in the same manner that all reverse units function by using forward, neutral and reverse states that are entered each time the throttle is turned on and off or by using the transformer direction switch (if so Proto-Coupler® Selection Switch equipped). The reverse unit is designed to ignore dirty track, dead spots on switches or minor short circuits without disrupting the engine Figure 1: Locating The Proto-Coupler Selection Switch operation, even at slow, prototypical speeds. Once the engine is placed on the track, the throttle on the transformer can be Neutral advanced. You will see that only the RESET Forward Reverse engine’s lights come on and that only two Neutral dings of the Proto-Sound® bell occur Figure 2: DCRU™ Cycle Phases followed by the blower sounds (on Proto-Sound® equipped 3-rail models). The engine does not run. This is known as the RESET state and is explained in more detail beginning on Page 4. The Proto-Sound® DCRU® will not power the motors until the throttle is turned OFF and then ON again. At this point, the engine will now function just like any other electronic or mechanical E-unit. 3 P-2 Box Cab Operating Manual PROTO-SOUND® INSTRUCTIONS The MTH Proto-Sound® digital sound and train control system provides the operator with unprecedented realistic operation on your model railroad. In addition to actual electric engine, CD-equivalent 16-bit digital sounds, you get the following features: 1. * Built-In DCRU Reverse Unit * Authentic Electric Engine Whistle Sound * Authentic Electric Engine Bell Sound * Squeaking Brake Sound * Passenger Station Announcements * Operating Remote Controlled ProtoCoupler™ * Self-Recharging Battery Back-Up System With Automatic Battery Shut-Off * Remotely Controlled Reverse Unit Lock-Out * Remotely Adjustable Electric Engine Volume * Ungradable Microprocessor Options * Random Selection of Four “Cab Chatter" Radio Transmission Sound Clips * Authentic Electric Shut Down Sounds Each feature is described among the following pages. Though the system is easy to use, we encourage you to read the instructions thoroughly. Proto-Sound® DCRU® REVERSE UNIT As mentioned in the Basic Operating section, the engine is controlled by a Proto-Sound® DCRU® reverse unit that contains the standard forward-neutral-reverse states found on most reverse units. However, as described earlier, when power is first applied to the track, the reverse unit begins in RESET or what seems like a neutral state. Power must be interrupted again to get the locomotive to enter the forward state. It is this first RESET state that gives Proto-Sound® its unique, remote controlled functions. The system will enter RESET whenever power to the track is off for three or more seconds. NEUTRAL will be referred to as the state between Forward and Reverse. ProtoSounds® is equipped with a microprocessor that, depending on the amount of memory it is allotted, allows the user to utilize several remotely activated functions. In the simplest terms, Proto-Sound® has its own “Computer" controlling these functions. In order to access many of these remotely controlled functions, the user must be in the RESET state to do so. RESET is entered anytime power to the locomotive has been off for more than 3 to 5 seconds. When the engine first enters RESET, the microprocessor initiates a system check to determine if the system, transformer and engine are operating correctly. This takes approximately 2.2 seconds during which you will hear the engine’s blower sounds begin. 4 P-2 Box Cab Operating Manual In order for Proto-Sound® to properly initiate the system check, do not advance the transformer throttle past 10 volts when you first enter RESET, wait for the electric startup sounds to begin and then slowly turn the transformer throttle to the off position and then back on again to enter the forward phase. Interrupting the power too quickly may cause the system to re-enter RESET (signaled by two dings of the bell). Should this happen, wait longer before interrupting the power to enter the Forward phase. Proto-Sound® comes with several programmable functions, including Engine Volume Adjustment, Separate Bell Button Operation (pre-programmed at the factory), Cab Chatter On/Off Control, ProtoCoupler On/Off Control and Horn-In-Neutral Operation. Each of these features are described in more detail later. You will notice that when in RESET, your engine will not respond to the whistle button with a horn blast or continuous bell ringing. In fact, when in RESET and the whistle button is depressed, only one single bell chime will be heard each time the whistle button is pressed. If you don’t want to configure or change your locomotive using any of these programmable features, simply leave RESET and wait 2.2 seconds before interrupting the power to put the engine in forward. After you leave RESET, your engine will operate normally in all the direction states of forward, neutral and reverse. WHISTLE OPERATION Your MTH P-2 Box Cab ProtoSound-equipped engine is equipped with a digital recording of a P-2 Box Cab Whistle. The whistle sound can be activated anytime the engine is in forward or reverse by pressing the whistle button on your transformer. The whistle will continue to blow as long as the whistle button is depressed. The whistle will not function in RESET and must be configured through a RESET option to allow the whistle to work when the engine is in neutral. See page 19 for information on whistle programming in the Using RESET To Program Proto-Sound® section of this manual. BELL OPERATION Your MTH P-2 Box Cab Proto-Sound® engine is equipped with a digital recording of an actual bell. Unlike previous versions of Proto-Sound®, the bell can be turned on or off with any separate bell button, like the Lionel® Railsounds® No.
